In Spark Datase, if we add additional column using
withColumn
then the column is added in the last.
e.g.
val ds1 = ds.select("Col1", "Col3").withColumn("Col2", lit("sample"))
the the order of columns is >> Col1 | Col3 | Col2
I want the order to be >> Col1 | Col2 | Col3
How can I achiev
I am deriving the col2 using with colunn which is why I cant use it like
you told me
